13 Imager::Color checks when deciding whether to skip testing it
14 http://rt.cpan.org/Ticket/Display.html?id=26064
16 - use a convolution kernel size based on the stddev rather than a
17 fixed size when performing a gaussian blur
18 http://rt.cpan.org/Ticket/Display.html?id=25645
20 - document the difference() method's mindist parameter, and debug it.
22 - put the Imager releaser number in the Inline::C generated code to

30 http://rt.cpan.org/Ticket/Display.html?id=11972
32 - reworked library probing, we can now set more than one probe
33 function for a library. Disabled the default (non-freetype-config)
34 library probe and added an extra probe function that searches for
35 both ft2build.h and whatever it includes, and adds -I as needed.
36 Hopefully this will fix build problems like

40 Imager 0.57 - 30 Apr 2007
43 This is a maintenence release fixing a security issue in Imager.
45 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
46 overflow in malloced memory. There will be further discussion of
47 this issue in the ticket below.
48 http://rt.cpan.org/Ticket/Display.html?id=26811
51 Imager 0.56 - 1 Apr 2007
54 - added support for reading 16-bit/sample PGM/PPM images
56 - added support for writing 16-bit/sample PGM/PPM images
58 - improved performance of reading PBM/PGM/PPM images
60 - added support for writing PBM images if the image is paletted and
61 contains only black and white
63 - added a new make_colors value - "mono"
65 - switched from the svn log Changes to a manual Changes to reduce
68 - new sample code - samples/flasher.pl
72 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
73 was returning an image object with an extra reference, this
74 resulted in a memory leak.
75 http://rt.cpan.org/Ticket/Display.html?id=24992
77 - fix rendering on alpha channel images for the FreeType 2.x driver
78 http://rt.cpan.org/Ticket/Display.html?id=11972

81 supply a parameter to treat a short read as successful and set
83 http://rt.cpan.org/Ticket/Display.html?id=8426
85 - previously, reading ASCII PBM files required spaces between samples,
86 even though the format doesn't require that
88 - improved documentation of the unsharpmask filter (I hope)
89 http://rt.cpan.org/Ticket/Display.html?id=25531
91 - force flushing of the output from i_tt_dump_names() and test output
92 in t/t35ttfont.t to prevent output from being mixed up.
93 https://rt.cpan.org/Ticket/Display.html?id=24859
95 - rewrite a conditional expression as an if() to hopefully work around
96 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
97 https://rt.cpan.org/Ticket/Display.html?id=25561
99 - avoid Data::Dumper in regops.perl to support older releases of perl
100 https://rt.cpan.org/Ticket/Display.html?id=24391
102 Imager 0.55 - 16 Dec 2006
105 This is primarily a bug fix release.
107 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
109 There is one new feature:
111 - the Win32 font driver now supports UTF8 (RT 22166)
112 http://www.cpanforum.com/threads/3276
113 http://rt.cpan.org/Ticket/Display.html?id=22166
115 Several bugs were fixed:
117 - the string() method would not output the string "0"
118 http://rt.cpan.org/Public/Bug/Display.html?id=21770
120 - fills.c was failing to compile on Solaris 10 (compiler unknown)
121 http://rt.cpan.org/Public/Bug/Display.html?id=21944
123 - the gif_disposal and gif_user_input tags weren't being read from
125 http://rt.cpan.org/Public/Bug/Display.html?id=22192
127 - gif.c was failing to build under MSVC
128 http://rt.cpan.org/Ticket/Display.html?id=23922
130 - in some cases strings passed to the string() method were treated as
131 terminated by NUL (chr 0)
132 http://rt.cpan.org/Public/Bug/Display.html?id=21770
134 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
135 that's the default build name for zlib on Win32.
136 http://rt.cpan.org/Ticket/Display.html?id=23064
138 - search $Config{incpath} for headers too, which we should have been
141 Win32 font driver fixes:
143 - the global descent value from bounding box was the wrong sign
144 http://www.cpanforum.com/threads/3276
146 - if the first or last glyph overflowed the left or right side of the
147 advance width they would be clipped
150 Imager 0.54 - 14 Sep 2006
153 This is primarily a feature release:
155 - a new qtype value 'mixing' has been added to the scale()
156 method. This is faster than 'normal', slower than 'preview'. This
157 is based on the method used by pnmscale, and seems to produce less
158 blurry results than normal.
159 http://rt.cpan.org/Public/Bug/Display.html?id=20677
161 - the rubthrough() method can now render onto images with an alpha
163 http://rt.cpan.org/Ticket/Display.html?id=20678
165 - the read_multi() method now falls back to calling doing a single
166 image read via the read() method and write_multi() will now fall
167 back to calling write() if a single image is supplied. This means
168 you can simply call the read_multi() or write_multi() functions
169 without having to check if the type is formatted by that method.
170 http://rt.cpan.org/Ticket/Display.html?id=19457
171 http://rt.cpan.org/Ticket/Display.html?id=19458
173 - the GIF loop extension can now be written. If you don't have
174 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
176 http://rt.cpan.org/Ticket/Display.html?id=21185
178 - getscanline() and setscanline() can now read/write palette index
179 based data from/to the image for paletted images, by setting type to
181 http://rt.cpan.org/Ticket/Display.html?id=20338
183 - we no longer hassle you to disable GIF support
184 http://rt.cpan.org/Ticket/Display.html?id=20687
186 - minor documentation fixes
189 Imager 0.53 - 26 Jul 2006
192 This is a bugfix release.
194 Some test code was left in a code path not covered by the test
195 suite. A test was added to cover this code path and the test code was
197 http://rt.cpan.org/Public/Bug/Display.html?id=20705
200 Imager 0.52 - 25 Jul 2006
203 This is primarily a feature release, but contains a fair few bug
206 - ability to read and write MS Windows ICO and CUR files
208 - you can now add file format plugins to support new file formats
210 - add POD coverage tests
212 - setcolors() and addcolors() now accept color names and so on
213 instead of requiring Imager::Color objects.
214 http://rt.cpan.org/Ticket/Display.html?id=20056
216 - flood_fill() can now fill to a specified border color instead of
217 just to the area the same color as the seed.
218 http://rt.cpan.org/Ticket/Display.html?id=19618
223 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
224 calculating the advance width.
225 http://rt.cpan.org/Public/Bug/Display.html?id=20554
227 - bounding_box for the T1 driver wasn't including leading and
228 trailing spaces in the bounding box as the other drivers did, it also
229 produced strange results for empty strings or strings containing only
232 - when reading CMYK jpeg images they were being transferred to the
233 image object as is, producing a four channel image. It only looked ok
234 due to an old still unfixed Photoshop bug. We now convert from the
235 inverted CMYK that photoshop (and Corel for example) produce into RGB.
236 http://rt.cpan.org/Ticket/Display.html?id=20416
238 - reading a CYMK TIFF would result in a 4 channel image, reading any
239 image with more than 4 channels (eg. RGB with 2 alpha channels) would
241 http://rt.cpan.org/Ticket/Display.html?id=20415
243 - added /usr/local/include to the default include search path, since
244 we were already searching /usr/local/lib for libraries.
246 And various minor fixes and documentation updates.
249 Imager 0.51 - 23 Apr 2006
252 - fix a validation bug when processing JPEG EXIF data that can cause
254 http://rt.cpan.org/Public/Bug/Display.html?id=18496
256 - fix mis-processing of the src_maxx and src_maxy parameters of the
258 http://rt.cpan.org/Public/Bug/Display.html?id=18712
260 - fix a problem in Imager's "smart" handling of the color parameter
262 http://rt.cpan.org/Public/Bug/Display.html?id=18561
265 Imager 0.50 - 29 Mar 2006
268 - CRITICAL: fixes a segmentation fault from attempting to write a 2
269 or 4 channel image to jpeg or a 2 channel image to tga where the
270 output is an in-memeory buffer.
271 http://rt.cpan.org/Public/Bug/Display.html?id=18397
273 - fixes an incorrect pointer parameter in the PNG code
274 http://rt.cpan.org/Public/Bug/Display.html?id=18051
276 - skip Inline::C tests when building in a directory with spaces
277 http://rt.cpan.org/Public/Bug/Display.html?id=18049
